Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall schematic diagram of a multi-party video push / pop service according to an embodiment of the present invention. The multilateral video push / pop service is provided to the mobile terminal of the user by the video push / pop server 200, and each mobile terminal may function as the push request terminal 100 or the pop service terminal 300. The push request terminal 100 and the pop service terminal 300 may communicate with the video push / pop server 200 through a communication network. The communication network may include a mobile communication network, a wireless internet network, a wired internet network, and the like. .

The video push / pop service provides a video push service and a video pop service using a mobile terminal. The video push service is a service that provides an image to a location designated by a user. The location you specify can be selected manually or automatically. In the case of manual selection, some of the subjects who can receive the image are selected to transmit the image. In the case of automatic transmission, the image can be automatically transmitted to a target person designated in advance, or automatically to a target person located locally.

The video pop service is a service that brings images from a user-specified point. A user may manually designate a point using map information and a point at which a push service is available, and a point corresponding to a condition may be automatically designated. For example, the condition may include a distance from the current location, a service available time, or whether the permission is provided. The selectable point may be a fixed location such as a CCTV camera, a police station, a fire station, a related server, or the like, or may be a variable and variable location such as a user's smartphone. In order to apply the pop service to a dynamic location, it is necessary to know the exact location information of the location.

The video used in the push pop service is generally captured in real time, but in some cases, the recorded video may be used.

The video push / pop service may be used for various purposes. For example, when an emergency situation such as an emergency situation or a crime situation occurs, the user may transmit his location information and real-time video information to the situation center by selecting a push service on the mobile terminal. The situation center searches for CCTV cameras around the site by using the received location information, requests pop services for specific CCTV cameras, acquires CCTV images around the site, and checks the status of the site or determines whether it is a real situation. can do. In addition, the situation center may transmit to a mobile terminal possessed by a cooperative group member who is authorized to receive the received video or CCTV image, for example, a police officer, a crime guard or an ambulance.

In addition, it may be used as a traffic accident reporting service or a nursing service for caring for a patient or an elderly person.

The push request terminal 100 may interwork with the image push / pop server 200 through a communication network and transmit the video to the image push / pop server 200 to transmit a video at a specific location photographed in the field to a designated point. In this case, the captured video may be transmitted together with the location information of a specific point. In addition, in order to provide a video pop service in the push request terminal 100, it is necessary to provide location information with high accuracy. In general, the position information collected using GPS has a very high average error of about 3 to 15 m, and thus a position information correction process is required to increase the accuracy of the position information.

The video push / pop server 200 processes the requests of the video push service and the video pop service. When the image push / pop server 200 receives an image push request for a designated point from the push request terminal 100, the image push / pop server 200 may transmit the received video together with the corresponding position information or to a position corresponding to the designated point alone. In addition, when receiving a pop service request, the video push / pop server 200 may acquire accurate location information of a corresponding designated point, and transmit a video and related location information to a point corresponding to the acquired location information.

When the pop service terminal 300 receives a pop service request from the push request terminal or the image push / pop server 200, the pop service terminal 300 provides desired image information together with location information.

The pop service terminal 300 may be a mobile terminal such as a smartphone, a feature phone, a tablet, a PMP, a laptop, or the like, or a fixed terminal such as a general PC or a server, or an image device such as a CCTV camera.

Next, a detailed configuration of the push request terminal will be described in detail with reference to FIG. 2.

2 is a detailed block diagram of the push request terminal 100 according to an embodiment of the present invention. As shown in FIG. 2, the push request terminal 100 includes a GPS module 110, a location information correcting unit 120, a camera module 130, an image processing unit 140, a push service unit 150, and a communication unit ( 160 and the pop service unit 170.

The GPS module 110 calculates information about a distance of one point away from three or more satellites, and information on a time at which the distance information is measured, and then applies a triangulation method to the calculated distance information, so that Two-dimensional position information according to latitude and longitude of a point or three-dimensional position information according to latitude, longitude and altitude can be calculated. Furthermore, a method of calculating position and time information using three satellites and correcting the error of the calculated position and time information using another satellite can also be used. The GPS module 110 continuously calculates the current position in real time and uses the same to calculate speed information.

The position information corrector 120 performs error correction using the plurality of position information acquired from the GPS module 110.

The location information corrector 120 may increase the accuracy of the location information by obtaining an average value using location information having relatively small errors among the plurality of location information. To this end, the position information corrector 120 obtains an average value and respective deviations of the plurality of position information, and calculates a variance value and a standard deviation using the same. Then, only deviations smaller than (or less than or equal to) the obtained standard deviation are selected, and average values of location information corresponding to the selected deviations are obtained.

The location information corrector 120 may calculate an average value using the plurality of location information extracted by the GPS module 110. For example, the position information corrector 120 may calculate an average value of the corresponding position information based on the 10 position information measured for 10 seconds. The location information may be two-dimensional data of latitude and longitude, and three-dimensional data of latitude, longitude and altitude. In this embodiment, the two-dimensional position information of latitude and longitude will be described as an example.

Thereafter, the position information correction unit 120 calculates a deviation that is a difference between the average value of the plurality of position information and the respective position information.

Thereafter, the position information corrector 120 obtains a variance value using the deviation value calculated for each of the position information, and calculates a standard deviation using the obtained variance value. The variance is obtained by averaging the square of each deviation. In addition, the standard deviation is a value obtained by calculating the square root of the obtained variance value.

Thereafter, the location information correction unit 120 selects location information having a deviation less than or equal to the standard deviation from a plurality of deviations, obtains an average value, and corrects the location information using the average value of the selected location information. do. In detail, the position information corrector 120 selects deviations having an absolute value less than or equal to the standard deviation among a plurality of deviations calculated for the plurality of position information.

Then, the average value is obtained using only location information corresponding to the selected deviations.

Thereafter, the position information corrector 120 corrects the corresponding position information by using the calculated average value. In other words, the position information corrector 120 may determine the calculated average value as position information on a position to be obtained.

Through the above process, it is possible to generate accurate position information having a relatively small error by filtering the position information which is determined to have a relatively large error compared to the average value, and obtaining an average value with only the position information having a relatively small error.

The camera module 130 processes image frames such as still images or moving images obtained by the image sensor in a video call mode or a photographing mode.

The image frame processed by the camera module 130 may be stored in a memory or transmitted to the outside through the communication unit 160 to be described later. Two or more camera modules 130 may be provided according to the configuration of the terminal.

The image processor 140 converts the image frame processed by the camera module 130 into a transferable state. In addition, the image processor 140 may process the video to be transmitted so that it can be played only in a specific device.

The push service unit 150 detects a push request input from a user and transmits a moving picture photographing instruction or a location information acquisition instruction to the camera module 130 and the GPS module 110.

In addition, the push service unit 150 receives information about a designated device to push a video from the user. In this case, the designated device may be selected from a list previously registered by the user or input through a map screen.

The communicator 160 transmits the video captured by the camera module 130 and the corrected position information through the position information corrector 120 to the image push / pop server 200.

The communication unit 160 may include one or more modules that enable wireless communication between the push request terminal 100 and the wireless communication system or between a network in which the push request terminal 100 is located. For example, the communication unit 160 may include a mobile communication module, a wireless internet module, a short range communication module, and the like.

The mobile communication module transmits and receives a radio signal with at least one of a base station, an external terminal, and a server on a mobile communication network. The wireless signal may include various types of data depending on a voice call signal, a video call signal or a text / multimedia message transmission / reception.

The wireless internet module refers to a module for wireless internet access. The wireless internet module may be embedded or external to the push request terminal 100. Wireless Internet technologies may include Wireless LAN (Wi-Fi), Wireless Broadband (Wibro), World Interoperability for Microwave Access (Wimax), High Speed Downlink Packet Access (HSDPA), and the like.

The short range communication module refers to a module for short range communication. As a short range communication technology, Bluetooth, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, and Near Field Communication (NFC) may be used.

The pop service unit 170 receives a list of devices providing the pop service from the image push / pop server 200 and requests a video to be provided to a specific device selected from the list.

In detail, the pop service unit 170 may request information of devices satisfying a condition from the image push / pop server 200, and select a desired device from a list of pop service providing devices transmitted in response to the request. .

In addition, the pop service unit 170 may make a request for providing an image to the selected device. In this case, the push request terminal 100 or the user may require an appropriate authority for the device.

In this case, the device providing the pop service may be a CCTV camera or another mobile terminal. For example, the push request terminal 100 transmits a video and position information of a specific position to the image push / pop server 200, and the image push / pop server 200 based on the transmitted position information, the surrounding CCTV The device information of the camera may be collected and provided to the push request terminal 100. Thereafter, the pop service unit 170 of the push request terminal 100 selects a specific CCTV camera based on the location information of the neighboring CCTV cameras received from the image push / pop server 200 and selects a CCTV image by the corresponding CCTV camera. You can request

As another example, the push request terminal 100 may request image information of another mobile terminal, and the image push / pop server 200 transmits a message requesting image provision to a corresponding mobile terminal according to the request. Received or previously received and stored image may be transmitted to the push request terminal (100).

Next, a detailed configuration of the image push / pop server 200 will be described in detail.

3 is a detailed block diagram of the image push / pop server 200 according to an embodiment of the present invention. As illustrated in FIG. 3, the image push / pop server 200 may include a push request processor 220, an image processor 230, and a pop service processor 240. In addition, the receiver 210, the transmitter 250 and another server interworking unit 260 may be further included.

The push request processor 220 receives the video and the location information from the push request terminal 100 and transmits the video to the device to be pushed.

In addition, the push request processing unit 220 may create a list of the video pop service providing apparatus that satisfies a specific condition using the location information received from the push request terminal 100 and provide the list to the push request terminal 100. .

For example, the push request processing unit 220 may analyze the location information of the push request terminal 100 and select mobile terminals providing a CCTV camera or a video pop service around the corresponding location. In FIG. 5, when conditions are determined by a CCTV camera or a mobile terminal located in a small circle centered on the push request terminal 100, the CCTV cameras 400-4, 400-5, 400-9 and the mobile terminal ( 300-4, 300-6) is selected. In this case, the push request processor 220 provides the push request terminal 100 with information about the selected CCTV cameras 400-4, 400-5, 400-9 and the mobile terminals 300-4, 300-6. In addition, the push request terminal 100 may request a video pop service by selecting a specific device from a list of received devices.

The image processor 230 converts the received video into a supported format of the device to be pushed. The image processor 230 may compress an image to be transmitted in advance so that the image may be efficiently reproduced and transmitted in the mobile terminal.

The pop service processor 240 receives an image providing request from the mobile terminal, receives the requested image from the request target device, and transmits the requested image to the mobile terminal. In this case, the request target device must be a device that provides a video pop service. In addition, the request target device may be a CCTV camera or another mobile terminal.

The other server linkage unit 260 supports the image push / pop server 200 to be linked with other external servers. The external server may be a server of an institution or an organization that receives the image captured by the push request terminal 100 or another mobile terminal. For example, the other server interworking unit 260 may automatically transmit the field image captured by the push request terminal 100 to a server of a fire station, a police station, or a security company as needed.

Meanwhile, the image push / pop server 200 may include a receiver 210 and a transmitter 250 for data transmission and reception with the push request terminal 100 and other mobile terminals.

The receiver 210 and the transmitter 250 may use an adaptive transmission algorithm to ensure transmission quality with the terminal in a wireless Internet environment and to reduce problems such as delay and jitter packet loss.

Next, a method of providing a video push / pop service will be described.

5 is a flowchart illustrating a method of providing a multi-party video push / pop service according to an embodiment of the present invention. In the present embodiment, a case in which the push request terminal 100 designates the pop service terminal 300 to push a video will be described as an example. In addition, the case of transmitting the CCTV image information of the surroundings to the pop service terminal 300 based on the current position information of the push request terminal will be described as an example.

First, the push request terminal makes an image push request using the pop service terminal 300 as a push target (S602).

Thereafter, the push request terminal generates a video and position information to be transmitted (S604). At this time, the captured video may be converted or compressed into a form that can be transmitted, and the position information undergoes a correction process to reduce an error.

Thereafter, the location information and the video information are transmitted to the image push / pop server 200 (S606).

The image push / pop server 200 may search for devices that provide a pop service around by using the transmitted location information, and provide information of the searched devices to the push request terminal. In some cases, the image push / pop server 200 may search for nearby CCTV cameras satisfying a specific criterion based on the location information (S608), and may request and obtain a CCTV image from the corresponding CCTV camera ( S610).

Thereafter, the video push / pop server 200 transmits the location information and the video information to the pop service terminal 300 that is a push target (S612). In this case, the image push / pop server 200 may transmit CCTV image information acquired together with the video information.

Referring to step S604 in more detail, in FIG. 6, when the push request terminal detects a push request from the user, the push service unit 150 instructs the GPS module 110 to acquire location information, and the camera module 130. Instructs the video to be taken (S702).

Thereafter, the GPS module 110 measures location information data for a specific location. Location information for a specific location may be measured by a certain number over a predetermined time (S704).

Thereafter, the position information correcting unit 120 corrects the measured position information (S706). In detail, the position information correcting unit 120 calculates an average value of the position information measured by a predetermined number, and calculates a deviation from each position information by using the calculated average value. In this case, the calculated deviation is equal to the number of location information. Thereafter, the position information correction unit 120 calculates a variance value using the calculated deviation, and calculates a standard deviation using the obtained variance value.

Thereafter, the position information correction unit 120 selects only position information corresponding to a predetermined condition among the position information and calculates an average value. Specifically, the position information correction unit 120 compares the deviation of the position information with the calculated standard deviation, selects only the position information having a deviation less than or equal to the standard deviation, and uses the same to obtain an average value. The obtained average value is much different from the standard deviation, that is, the average value calculated using only the remaining position information except for the position information having a large error, so that the error with the actual specific position is substantially eliminated.

Thereafter, the position information correction unit 120 uses the obtained average value as position information for a specific position. If there is no location information corresponding to the above condition, an average value of all location information may be used.

In step S708, the camera module 130 captures a video of the scene (S708). Thereafter, the captured video is converted into a supported format of the device to be pushed by the image processor 140. Also, the captured video may be compressed before transmission so that the captured video may be efficiently played and transmitted in the mobile terminal (S710).

Thereafter, the corrected position information and the post-processed image information are transmitted to the image push / pop server 200 (S712).

In another embodiment of the present invention, the video push / pop service may be configured to use location information of a subject to be photographed, not location information of a push request terminal.

In this case, the push request terminal may photograph a specific point or object, and receive a location of the point or object photographed on the map from the user and transmit the captured video with the video.

Alternatively, at least two push request terminals may be photographed at the same time to acquire a location of the corresponding point.

For example, in FIG. 8, a specific point is photographed using the first mobile terminal and the second mobile terminal, and the two captured images are transmitted to the image push / pop server 200. In this case, a direction such as an arrow indicating a photographing direction or a direction information measured by a gyro sensor may be added to the captured image. Thereafter, the image push / pop server 200 may analyze the received two images to determine location information of a specific point, which is a point where the location of the two terminals intersects based on the photographing location information of the two terminals.

The above embodiment can be used to provide a service for reporting an accident scene and the like.
